I've done it for groups I'm in, and it does nothing for sales in general. You might get a spike in facebook page interest, but if that translates into sales is another issue. The interesting thing is that when I do giveaways (not cakes, decorating supplies etc) on my business page I usually get a lot of entries, but then about half the time the person who won doesn't claim the prize. It's the same thing when my wedding association does giveaways. People will donate services ranging from limos to wedding planning, and 9 times out of 10 the winner doesn't claim the prize at all. I don't get it...

I always say, would I do that? Would I go to the effort of posting a picture of myself on a business page...probably not. And, the number of 'likers' will surely depend on who likes your page, who likes their page and what their sharing settings are, right? Maybe do a giveaway, but make it less effort for people?

I agree with the giveaways as well. I have donated 4 cake vouchers over the past 2 years - 3 to charity and 1 to my local netball team (I never make a cake freshly because the chances are, they won't have an occasion to eat an 8" chocolate fudge). Only 1 person ever claimed it. Go figure. x
